If you can’t provide the bare minimum space requirements that everyone seems to go by I’d love to see your chickens and how you keep them. Maybe I can learn something from you.
I’m not sure how old they are but as they mature you’ll see more issues. Having the hens so close within sight and hearing of the roosters will make it worse too.
It’s not that you can’t keep them in 100 sq feet. It’s just not wise. The more room they have the better they’ll get along and less problems you’ll have with them. The more room the healthier they’ll be too.
